Single-Use Bioprocess Assemblies worked example

Production Ramp Planner at 99% ramp-phase line uptime: a worked example in single-use bioprocess assemblies

What does the result look like when ramp-phase line uptime reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when production ramp planner in single-use bioprocess assemblies is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Assemblies built per ramp cycle: 4 units / cycle (unchanged)
  • Available ramp cycles in period: 480 cycles (unchanged)
  • Ramp-phase line uptime: 99 % (raised for this scenario; the documented default is 90)
  • Ramp-phase first-pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross production ramp planner capacity = production ramp planner output per cycle × available production ramp planner cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good production ramp planner capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross production ramp planner capacity.
  • At this operating point the engine returns 19.2 units for production ramp planner downtime loss.
  • At this operating point the engine returns 57.02 units for production ramp planner yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where ramp-phase line uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when ramp-phase line uptime is genuinely sustained, not just peaked for a shift. It applies one flat uptime and one flat yield across the period; a real ramp improves week over week, so split the ramp into stages and run each stage separately for an accurate curve.

Results at a glance

  • Good production ramp planner capacity: 1,844 units (headline result)
  • Gross production ramp planner capacity: 1,920 units
  • Production ramp planner downtime loss: 19.2 units
  • Production ramp planner yield loss: 57.02 units
